Structure and working principle:

1、 Structural composition

A rotating electromagnet is similar to the rotation of a motor, but the difference between a rotating electromagnet and a motor is that the motor can continuously rotate in one direction forever, while a rotating electromagnet will not continue to rotate after being powered on to a specific angle. After being powered off, it will move back and forth through its built-in reset spring to complete a certain task. Because it can only rotate in a specific area, it is called a rotating electromagnet or angle electromagnet. From the direction of rotation, it can be divided into two types: clockwise rotation and counterclockwise rotation.

2、 Working principle

The principle structure of a rotating electromagnet is to magnetize the iron core and armature into two opposite magnetic poles after the electromagnetic coil is energized. Electromagnetic attraction will be generated between them. If the generated attraction is greater than the return force of the reset spring, it will drive the iron core to rotate a certain angle. When the current of the electromagnet decreases to a certain degree and the attraction force is lower than the return force of the spring, the electromagnet will return to its previous position. The rotating electromagnet uses the magnetic force of the iron core to control mechanical equipment to achieve a certain action and complete a certain task. It can be applied to many mechanical equipment or products.
